The firm's executive committee will consist of Tom Durkee, Ed Hofma, Ron Person, Steve Petosa, and Jim Warmus, according to the company. Warmus will continue to serve as CEO.

"Our decision to merge at this time is reflective of each firm's desire to offer expanded opportunities for employees and increased resources for clients, including membership with the PKF North American Network of independent CPA firms," said Warmus. "We have become bigger and better as a result of the merger."

Richard Pilhorn, a partner at Osburn, Henning and Company, said, "We are thrilled about what this merger means in terms of capabilities. Our combined strength means we can provide a wide array of large-firm services without the overhead of a national company."
